Social anxiety is a type of anxiety problem. People with social anxiety can usually interact easily with family and a few close friends. Instead of enjoying social activities, they might fear them and avoid some of them altogether. Like other anxieties, it is a fear reaction to something that isn’t actually dangerous, although the body and mind react as if the danger is real. Because the physical sensations that go with the response are real and sometimes quite strong the danger seems real. With social anxiety, a person’s fears and concerns are focused on the social performance whether it’s a major class presentation or small talk at the lockers. People tend to feel embarrassed and uncomfortable about being noticed or judged by others.

Social anxiety might prevent someone from chatting with friends in the lunchroom, joining an after-school club, going to a party, or asking someone on a date. It might keep a person from volunteering an answer in class, reading aloud, or giving a presentation. It might prevent someone from acting the school play, being in the talent show, trying out for a team, or joining in a service project. It also prevents them from making the normal, everyday mistakes that help people improve their skills still further.

Social anxiety develops because the genetic features from parents and other relatives can influence how the brain senses and controls anxiety, shyness, nervousness, and stress reactions. Meanwhile, some people are born with a shy character and tend to be cautious and sensitive in new situations and prefer what’s familiar. Naturally a person’s shy character can be influenced by what he or she learns from role models. If parents or others react by overprotecting a child who is shy, the child won’t have a chance to get used to new situations and new people. If people born with a cautious nature have stressful experiences, social anxiety can make them even more cautious and shy. Feeling pressured to interact in ways they don’t feel ready for, being criticized or insulted, or having other fears and worries can make it more likely for a shy or fearful person to develop social anxiety.

Sometimes, but not always, medicines that reduce anxiety are used as part of the treatment. Family or friends are especially important and the right support from a few key people can help those with social anxiety gather the courage to go outside their comfort zone and try something new. Dealing with social anxiety takes patience, courage to face fears and try new things, and the willingness to practice.
